A GP100 4" and a 686P 3".
And just the GP100.
I like the Ruger, it is solid, easy to shoot, double action trigger is smooth, single action trigger is fine, too. Currently I use it in IDPA practice sessions, a wonderful thing for that purpose.
But I also like my S&W 686P, M&P R8, 19, Ruger Security Six. Hard to choose between them, they are all splendid 6-7-8 shooters.
